Abstract

The utility model relates to a gas valve which is used for reducing subpressure and opening a freezer, mainly composed of a valve body [8] and an opening handle [4]. The freezer is scooped at the positioned near to a sealing layer [9] of a handle [3], the valve body [8] is arranged in a hollow cavity, an air outlet [11] of the valve body [8] penetrates through the sealing layer [9] and the inner wall [13]of the freezer and outwards exposes in the freezer, the opening handle [4] is arranged in the handle [3] of the freezer, and the opening handle [4] is provided with a resetting spring [6]. The utility model has the advantage of simple structure, low cost, and convenient assembly, and the phenomenon of subpressure in the freezer can be eliminated and a cover of the freezer is easy to open when the utility model is used.

Description

Refrigerator-freezer is opened the Reduction of Students' Study Load pressure valve

The utility model relates to a kind of air valve, and a kind of specifically refrigerator-freezer is opened the Reduction of Students' Study Load pressure valve.

At present, though refrigerator-freezer has good door envelope effect, owing to be in low-temperature condition in the refrigerator-freezer, the hot-air that enters by the environment contraction of catching a cold rapidly, cause to be negative pressure state in the refrigerator-freezer, like this door of refrigerator-freezer just extremely difficulty open, often owing to open the door firmly excessive, break or draw the damage handle, the door closure surface often produces convex-concave and alternately changes, and the cabinet mouth plane of outer wall of refrigerator-freezer and pressure that gasket seals also is subjected to influence in various degree, and gasket moves down with door closure, the elasticity that is crushed weakens, and influences its insulation effect.The disclosed horizontal chest freezer of the patent No. [92219633.8] air pressure balance protector; it is characterized in that whole L-shaped; divide hard straight planar section and level to be Ω shape bent face part; porose on the perpendicular part; its level is Ω shape bent face part and extend into refrigerator-freezer inside on the refrigerator-freezer cabinet mouth under the gasket during use; the perpendicular part is then utilized freezer door to cover original hinge bolt by the hole on it and is fixed on the door closure; close after the cabinet lid; the outer air of refrigerator-freezer still can enter by the slotted hole under the bent face in the refrigerator-freezer; but influenced the sealing effectiveness of refrigerator-freezer like this, reduced the refrigeration of refrigerator-freezer.

The purpose of this utility model is to provide a kind of Reduction of Students' Study Load pressure valve that freezer cover is opened of being convenient to.

The technical solution of the utility model is: refrigerator-freezer is opened the Reduction of Students' Study Load pressure valve and mainly is made up of valve body, unlatching handle, valve body mainly is made up of air inlet, gas outlet, the employing soft rubber material is made, the sealant of the close handle of refrigerator-freezer is dug a cavity, valve body places in the cavity, and valve body is fixed in the sealant cavity by a thin little fixed mount, and it is characterized in that: the valve body gas outlet is passed sealant and exposed in the refrigerator-freezer, open handle and place in the refrigerator-freezer handle, open on the handle and be equipped with back-moving spring.

The utility model is simple in structure, and cost is low, easy to assembly, uses it to open the refrigerator-freezer door closure easily, to prolong the service life of refrigerator-freezer.

Fig. 1 is a main TV structure schematic diagram of the present utility model.

Fig. 2 is a valve body structure schematic diagram of the present utility model.

Below in conjunction with embodiment and contrast accompanying drawing the utility model is described further.

Valve body of the present utility model [8] can adopt soft rubber material to make, open handle [4] and be inverted "L" shaped, be fixed on the refrigerator-freezer handle [3] by set bolt [2], it vertically partly is with seal [7], open on the handle [4] and be equipped with back-moving spring [6], being held open can in time reset after handle [4] is opened contacts with the air inlet [10] of valve body [8], keeps the sealing effectiveness of refrigerator-freezer.Valve body [8] is the L type, and part is exposed rectangle gas outlet [11] anyhow, Qi Kou two ends projection, and intermediate recess, the vertical portion is divided into circular air inlet [10].Valve body [8] places in the cavity of refrigerator-freezer sealant [9] by a fixed mount, the hole [5] that has the gas outlet [11] of its diameter and valve body [8] to adapt on sealant of refrigerator-freezer [9] and the refrigerator-freezer inwall [13], the gas outlet [11] of valve body [8] is then passed this hole [5] and is exposed in the refrigerator-freezer, avoids cold air to condense into water droplet like this and too much causes icing formation of air valve to be stopped up.During use, press and open handle [4], open with an end of the contacted unlatching handle of air inlet [10] [4] of valve body [8], the outer air of refrigerator-freezer just can enter in the refrigerator-freezer by air inlet [10], eliminated the negative pressure appearance in the refrigerator-freezer, the refrigerator-freezer door closure has also just been opened easily.

Claims

1, refrigerator-freezer unlatching Reduction of Students' Study Load pressure valve mainly is made up of valve body [8], unlatching handle [4], valve body [8] mainly is made up of air inlet [10], gas outlet [11], refrigerator-freezer hollows out near the sealant of handle [3], valve body [8] places in the cavity, valve body [8] is fixed in the sealant [9] by a very thin little fixed mount, it is characterized in that: valve body [8] gas outlet [11] passes sealant [9] and refrigerator-freezer inwall [13] exposes in the refrigerator-freezer, open handle [4] and place in the refrigerator-freezer handgrip [3], open on the handle [4] and be equipped with back-moving spring.

2, refrigerator-freezer according to claim 1 is opened the Reduction of Students' Study Load pressure valve, it is characterized in that valve body [8] is the L type, and part is exposed rectangle gas outlet [11] anyhow, Qi Kou two ends projection, and intermediate recess, the vertical portion is divided into circular air inlet [10].
